I have used lambda_g/4. I forgot typing it. I tried to simulate a shaped probe insted of simple coaxial probe, and now it works fine. I searched for some litterature and it has something to do with the capacitive reactance from the probe:

Thank you for your reply.
I have tried to simulate with a larger boundary on the back side, but it didn't not work. I have aldo tried to sweep the cavity depth, and it does work for some of the values. However, accoring to the equations for standard waveguide, it is given that the depth of the...
Hello.
I am trying to simulate a waveguide using HFSS. The dimensions are calculated using the standard equations for TE10 mode.
In the first model, I used a cut-off frequency of 2 GHz and a center frequency of 4 GHz (waveguide_2GHz.rar). The simulations seams to work, and I get a good s11...
Hello.
I am trying to simulate a simple waveguide using wave port in both ends. All seems to work, but I get several warnings saying:
Discrete solution, process hf3d: Port Port1 supports an additional propagating and/or slowly decaying mode whose attenuation is xxxx and propagation constant...
